用于签署交易的 Litecore-lib 函数无法正常工作

Question

我正在尝试使用 litecore-lib 包在莱特币测试网上创建交易。我附上代码片段。我打印每一行来分析交易是如何建立的。调用 'sign' 方法时没有变化。

const litecore = require('litecore-lib');

var wif = 'cRkP6k8dDab1PDg2SvS8mbKMSxCSJfDFg6hibkKGmrfaU4xaCi9R';
var privateKey = new litecore.PrivateKey(wif, 'testnet');
var address = privateKey.toAddress('testnet');

console.log("Private key:", privateKey.toString());
console.log("WIF Private key:", privateKey.toWIF());
console.log("Address: ", address.toString()); //mmQQ2Mz1UGWtos6fGmM6sTg69itJmvxW9h



var utxo = {
  "txId" : "d095e2e921ac6f0ed5f7f886529c14d662b82feb35e1afa0051a8328855ecdf8",
  "outputIndex" : 0,
  "address" : address.toString(),
  "script" : "76a91447862fe165e6121af80d5dde1ecb478ed170565b88ac",
  "satoshis" : 100000,
  "network":'testnet'
};

var transaction = new litecore.Transaction()
console.log("\nTx Created:");
console.log(transaction.toString());

console.log("\nAdd input:");
transaction = transaction.from(utxo)
console.log(transaction.toString());

console.log("\nAdd output:");
transaction = transaction.to('mi1gqn4z9r1sm4XDjrTS8hegEaAMxYGWkW', 98000)
console.log(transaction.toString());

console.log("\nChange:");
transaction = transaction.change(address.toString())
console.log(transaction.toString());

console.log("\nFee:");
transaction = transaction.fee(1100)
console.log(transaction.toString());

console.log("Is fully signed:", transaction.isFullySigned());

console.log("\nSign:");
transaction = transaction.sign(privateKey)
console.log(transaction.toString());

console.log("Is fully signed:", transaction.isFullySigned());

下面附上输出。请对比签名前后的tx字符串：是一样的！

Answer 1

确保为您的 utxo 设置了正确的脚本。

var utxo = {
  "txId" : "d095e2e921ac6f0ed5f7f886529c14d662b82feb35e1afa0051a8328855ecdf8",
  "outputIndex" : 0,
  "address" : address.toString(),
  "script" : "76a9144093522294655efcbfc2bdfdb448682bf3bef69a88ac",
  // "script" : "76a91447862fe165e6121af80d5dde1ecb478ed170565b88ac",
  "satoshis" : 100000,
  "network":'testnet'
};
